Title: Method and device for generating tracking control signal of light beam for scanning track of information medium
Inventor: JIYANNRUI JIERAARU
IPC: G11B7/007
Filed: 1991-06-25
Abstract: PURPOSE: To enable accurate tracking control by sequentially detecting marks formed deviating from the center axis of a track between recording areas of information and comparing the amplitude of a read signal of a specific analytic window. CONSTITUTION: A sector starts with a coded flag 74 and then blocks of a right- side part 710-D, a use information data write area 72, a right-side part 710-G, and an area 72 are repeated. Pairs of parts which deviate in mutually different directions form two columns of analytic windows F1 -F2+1 and F2 -F22n . A photoelectric detecting means 10 of an optical detecting and signal processing means 1 generates an output signal VD, and supplies it to a generating circuit 11 for a tracking error signal and to a sampling circuit 12. The circuit 12 detects the deviation parts 710-D and G passing and sends out control outputs S1 and S2 corresponding to the respective analytic windows to switches 110 and 111 alternately. Consequently, the signal VD is transferred to a integrator 112 only at the time of the analytic windows, and a signal ε is generated according to their comparison output.

Title: Acg circuit for optical disc reader
Inventor: HIGUCHI YOSHIO
IPC: G11B7/125
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To shorten the term during which a comparator is disabled from binary coding even when the level of a reproduction signal varies a great deal by setting the time constant of a control signal for controlling the gain of a variable gain amplifier at a value shorter than the time that allows a pickup to readout the minimum data block. SOLUTION: A reproduction signal 31 sent out from a pickup 8 enters a variable gain amplifier 4 after a low frequency component from the frequency band of the reproduction signal 31 by a capacitor C1 as filter. The variable gain amplifier 4 amplifies the reproduction signal 32 passing through the filter based on a gain set by a gain control circuit 5 to be sent to a comparator 6. The gain control circuit 5 changes the level of a control signal 35 so that the level of the reproduction signal 33 to be outputted from the variable gain amplifier reaches that as target value. In this point, the time constant of the control signal 35 for controlling the gain is set with a capacitor C2 and a resistor R1 at a value than the time that allows the pickup 8 to read out each of the minimum data blocks.
